Checking a Third-Party Cabinet

Ground bearing of the equipment room

Does the ground bearing capacity of the equipment room meet requirements?

□Yes □No

The total weight of the cabinet and all devices, PDUs, and components in the cabinet does not exceed the ground bearing capacity of the equipment room.

Cabinet parameters

Is the cabinet a 19-inch standard cabinet (in compliance with the IEC 60297 482.6 mm (19") standards)?

□Yes □No

The size meets the requirements shown in Figure 7-4.

Is the cabinet empty?

□Yes □No

A third-party cabinet must be empty to ensure it has the capacity expansion capability.

Is the depth (L) at least 1200 mm? See Figure 7-5.

□Yes □No

For details about how to check whether the cabinet depth meets the installation requirements, see Cabinet Space Planning.

Does the cabinet have adequate space for installing the enclosure?

□Yes □No

Check whether the cabinet has adequate space for installing Huawei devices. Each controller enclosure occupies 4 U, and each disk enclosure occupies 2 U or 4 U.

What is the shape of the holes on the mounting bar?

□ Square hole (side length ≥ 9.5 mm x 9.5 mm)

□ Round hole (diameter ≥ Ф 7 mm)

N/A

Is the distance between the front and rear mounting bars (L2) ranges from 600 mm to 900 mm? See Figure 7-5.

□Yes □No

If a third-party cabinet has guide rails or trays, skip this item.

Do the guide rails delivered with the third-party cabinet meet the load-bearing requirements?

□Yes □No

A 4 U controller enclosure can support 97 kg.

Is the distance between the front mounting bar and the rear door (L3) at least 1000 mm? See Figure 7-5.

□Yes □No

If the distance is less than 1000 mm, cables at the rear of the storage device will affect proper cable routing.

Is the distance between the front mounting bar and interior side of the front door (L1) at least 50 mm? See Figure 7-5.

□Yes □No

If the distance is less than 50 mm, the mounting bar will affect closing of the front cabinet door.

Is the angle of the door when open at least 120º?

□Yes □No

A small angle hinders the loading, unloading, and maintaining of devices.

Cabinet power system

What is the AC power nominal voltage (V)?

□ 220 V AC

The server supports 220 V AC.

Does the cabinet require a dual-channel PDU?

A disk enclosure requires 1+1 power supply and a controller enclosure requires 2+2 power supply.

□Yes □No

• 220 V AC single-phase, 32 A
• 380 V AC three-phase, 32 A

Does the power system meet power supply requirements?

□Yes □No

The power system must be able to support the total maximum power consumption of all devices in the cabinet. You can query the maximum power consumption of Huawei devices on the Power Consumption Calculation or from the "Electrical Specifications" in Specifications Query.

Does the power of each PDU group meet the requirements?

□Yes □No

Each PDU group must be able to support the total maximum power consumption of all devices in that group. You can query the maximum power consumption of Huawei devices on the Power Consumption Calculation or from the "Electrical Specifications" in Specifications Query.

Does the power plug of the PDU face toward the rear door?

□Yes □No

If the power plug of the PDU faces toward the side, the FRU cannot be installed properly.

Is the PDU width greater than 50 mm?

□Yes □No

If the PDU width is greater than 50 mm, the PDU may interfere with the device, affecting the removal and installation of interface modules.

Are there sufficient power sockets (C13 standards) available on each PDU of each cabinet?

□Yes □No

The number of power sockets required by each device is as follows:

• 4 U controller enclosure: 4
• 2 U disk enclosure and 4 U disk enclosure: 2

Are there at least 20 power sockets (10 A) available on each PDU of each cabinet?

What is the power socket type?

__________

□ IEC standards

C13

Each server and each LAN switch requires 1+1 power supply. The KVM requires one power supply.

Depending on whether a customer requires one or multiple fully-configured cabinets, deliver the appropriate SAS cables and power cables. Each cabinet must provide C13 ports. If this cannot be met, replace the PDU onsite or use cables that match the PDU.

Is there a ground point?

□Yes □No

For the ground points in a 19" standard cabinet, M6 screws are needed. You should at least reserve the ground points for the KVM and data switch.
